I-E96-313A
®
Termination Unit (TU) or Termination Module (TM) (refer to
Table
). The terminal blocks (physical connection points) for
field wiring are on the TU/TM.
FEATURES
The modular design of the DSO, as with all Infi 90 modules,
allows for flexibility when you are creating a process manage-
ment strategy. It outputs sixteen separate digital signals to the
process. Open collector transistors in the output circuits can
sink up to 250 mA to a 24 VDC load.
The front panel LEDs provide a visual indication of the module
status to aid in system test and diagnosis. You can remove or
install a DSO module without powering the system down.
